It must be 21.3 feet.
The sides of the triangle given to us are the side opposite the angle to the ground, 20, and the missing side is the hypotenuse.
opposite/hypotenuse is the ratio for sine:
sin 70 = 20/x
Multiply by x:
x sin 70 = 20
Divide both sides by sin 70:
(x sin 70)/(sin 70) = 20/(sin 70)
x = 21.283 ≈ 21.3
M+2/3=1/2
<=> m= 1/2 - 2/3
<=> m= -1/6
Answer:
Step-by-step explanation:
To find the reciprocal of a fraction, simply switch the numerator and denominator.
Since is a mixed number, start by converting it to a common fraction using
Therefore, as a common fraction is:
Now switch the numerator and denominator to find the reciprocal:
